Rep. Justin Amash is running for president

Michigan Rep. Justin Amash (I) has announced he is launching a 2020 presidential bid to become the nominee for the Libertarian Party.

What are the details?

In a Twitter post on Tuesday, the former Republican shared a link to his campaign website with the message, "Let's do this," before explaining, "Today, I launched an exploratory committee to seek the @LPNational's nomination for president of the United States. Americans are ready for practical approaches based in humility and trust of the people."

He added, "We're ready for a presidency that will restore respect for our Constitution and bring people together. I'm excited and honored to be taking these first steps toward serving Americans of every background as president."

In a statement on his campaign website, Amash writes:

We're ready. For something new. For a government that secures our rights. For equality before the law. For an end to cronyism. For a government that fulfills its purpose and recognizes its limits. For practical approaches based in humility and trust of the people. For an honest, principled president who will defend the Constitution and put individuals first.

Who is Justin Amash?

Rep. Amash was elected to the U.S. House of Representatives as a Republican during the Tea Party tidal wave in 2010. He became a founding member of the House Freedom Caucus.

Amash is known for his knowledge of the Constitution, and for explaining the reasoning behind his votes via social media for his constituents. He is also known for taking a principled stand, even when he might stand alone.

The congressman was the sole House Republican to call for moving forward with impeachment proceedings against President Donald Trump, in May of last year. Amid uproar from the party, he left the Freedom Caucus in June, so as not to be "a further distraction from the group."

The next month, Amash left the Republican Party, declaring his "Independence" in a July 4 op-ed for The Washington Post, wherein he declared that "our politics is in a partisan death spiral."
